The Pole says that the omens favour his current side over his former one.
With 13 places separating the third-placed Gunners and relegation-threatened Swansea, it should, on paper, be a routine victory for Arsene Wenger's side at the Emirates tomorrow.
Having said that, the Swans know a thing or two about upsetting their North London counterparts, having beaten them in three of the last four Premier League meetings - including a double under ex-manager Garry Monk last season.
Fabianski, who spent seven years at Arsenal before joining City in 2014, acknowledges that his former club are chasing a league title, but hopes history can repeat itself.
"Arsenal are up there fighting for the title and they are very dangerous at home," the Pole is quoted as saying by BBC Sport.
"But we like to play against them and we hope it can be a good game for us."
With three points separating them from the drop zone, first-team coach Alan Curtis will be desperate to see his side improve their survival prospects with another shock win at Arsenal.
This will be their second trip to North London in the space of a few days, having lost 2-1 at Tottenham Hotspur on Sunday, despite going ahead through Alberto Paloschi.
